Understanding Capacity Utilization: Definitions and Measurements in China
Capacity utilization in China is a critical metric that measures the efficiency of industrial production. It is defined as the ratio of actual output to production capacity, both typically measured by value. This metric helps assess how well industries are utilizing their resources to generate output. The primary source for this data is the National Bureau of Statistics (NBS) of China, which conducts quarterly surveys involving approximately 110,000 industrial enterprises. These surveys cover large and medium-sized enterprises comprehensively, while micro and small enterprises are assessed through a sample survey method.
The NBS methodology involves extrapolating data from smaller enterprises to synthesize with larger firms' data, calculating the national industrial capacity utilization rate. For instance, in Q4 2025, the nationwide capacity utilization rate stood at 74.9%, slightly up from Q3 but down from Q4 2024. Understanding this process is essential for industry stakeholders aiming to optimize their production strategies and align with national benchmarks.
